A thermistor can be used to measure temperature.
An environmental scientist wants to monitor the temperature inside a greenhouse. The temperature in the greenhouse typically varies between 10∘C10^\circ\text{C}10∘C and 30∘C30^\circ\text{C}30∘C.
Which of the four thermistors, P, Q, R, or S, would be the most suitable to measure the temperature inside the greenhouse?
Explain your answer.
